Another perspective on the shaft of precipitation evident from towering Sunday's frontal cumulus clouds

Tyler Christiansen e-mails this shot of Sunday's precipitation producing towering
cumulus and asks if they are some sort of snow squall or snow rollers. What you're
seeing Tyler is swath of falling snow which would, given the powerful winds in play
Sunday, come closest to a snow squall. Great shot—thanks Tyler.
